The estimation of material crack-life and programme
Abstract
This design is mainly research and analysis of crack in the calculation of life and expressioncalculation method,Research and analysis crack strength life estimation of expression and estimation methods, And the preparation of these cracks in the intensity of expression procedures.Finally, good procedures for calculation of the number of data verification, and verified to see whether similar to those of experimental data, so that research by the expression is correct. Besides it provides a lot of new calculation equations on the strength and life, that it will be having practical significance to explain the profound things in a simple way to understand, accept and apply for intersectional correlations among the material-, damage-, micro-fracture-, macro-fracture-, mechanics.
Key Words: crack strength, Life expectancy estimates, Procedures, Fatigue and Fracture.
